The 166th Air Refueling Squadron is a unit within the United States Air Force that specializes in air-to-air refueling operations. It operates out of March Air Reserve Base, California, and falls under the jurisdiction of the Air Mobility Command. The squadron’s primary role is to extend the operational reach of other aircraft by providing them with mid-flight fuel, thereby enabling longer missions or increasing overall mission capability. The 166th ARS operates the KC-135R Stratotanker, a versatile refueling platform capable of carrying both aerial refueling boom and drogue systems for various receiving aircraft. The squadron’s history dates back to 1942, serving in World War II, the Korean War, the Vietnam War, and numerous other operations since then. Today, the 166th ARS continues its mission in support of U.S. military and allied forces around the globe.
